Geissler Tubes
Why does each tube emit a different colored light?
In this project, we notice each gas-filled tube emits a different color when an electric current is added. Why is that? Let's find out!
Geissler Tubes is a generic name given to these vacuumed tubes. Since each tube has a different set of properties from the rest, be it a difference in pressure or element gas, we are able to see it when it glows.
For this project we will use:
Tesla Coil
Geissler Tubes
Set filled with regular air set at differing pressures: 40 mmHg, 10 mmHg, 3 mmHg, 1 mmHg, 0.1 mmHg, 0.02 mmHg
Set filled with different gas elements: Hydrogen, Neon, Carbon Dioxide, Argon
Safety Regulation
The Tesla Coil is capable of reaching very high voltages of electricity. Proceed with this experiment with care and under adult supervision. The Geissler Tubes are very sensitive as well. They should be handled with care.
